This letter is a summary of a letter received from the President of Interstate Battery of Detroit.  Please contact  us if you would like the full letter mailed, faxed or e-mailed to you.

I am writing to let you know how pleased I am with the AMSOIL program that you helped set us up with.  For the past 25 years our fleet of trucks, mostly Navistar/International 4600 Series trucks, have been using regular petroleum-base lubrication products. We thought that we were happy with our lubrication program until we were introduced to AMSOIL.

I was very reluctant to switch from regular lubricants to fully synthetic lubricants because the benefits of AMSOIL seemed too good to be true.  To be honest, when I was told that the motor oil could go as long as 100,000+ miles without changing, I didn't believe it.  I can tell you now I am a true believer.

We have been using AMSOIL now for about 4 years and have changed the entire fleet to AMSOIL synthetic lubricants.  We use the By-Pass oil filtration system on all of our trucks with the Synthetic Heavy Duty Diesel and Marine 15W-40 oil.  We use AMSOIL grease and use the 75W-90 gear lube for the manual transmissions and differentials and the synthetic ATF transmission fluid for the automatics.

What do I get out of using AMSOIL?  A lot!! After becoming fully synthetic on all of my trucks, I picked up an average of 5% in fuel savings.  I haven't had to change my oil since I switched...4 years ago!  I can't tell you how much money that has saved me in time alone.  I have several trucks with over 100,000 miles on the oil and I am still getting high marks when I send the oil in for analysis  But the best benefit is the decreased wear and tear on my equipment such as the pistons, cylinder heads and walls, transmission gears and differential gears. That is the most important to me because it means I can leverage my fleet longer, which translates into saved dollars. It means I can put those extra dollars to work in another area of my business. My average truck life has gone from 7 years to more than 15 years! UNBELIEVABLE!  I have estimated the savings from better leverage alone will save me over $20,000 per year.

Thanks for all the help as I've implemented this new program. I am absolutely ecstatic about the results so far and I look forward to a long and fruitful partnership with you and AMSOIL.

Nelson Trucking enjoys BIG savings
Rock, Michigan - When Nelson Trucking and Forestry owner Roy Nelson's new Kenworth truck reached 15,000 miles, he replaced the factory oil with AMSOIL 15w-40 Heavy Duty Diesel and Marine oil. An AMSOIL Dual Gard by-pass system was installed and a regular oil analysis program was started. Since then he has known nothing but success and money savings.

At approx. 40,000 miles, Roy calculated that he saved some hard earned cash. He figured if he traveled 100,000 miles in the first year, just in fuel savings alone, he would see savings of $1,930.00 or about 8.4%.

When Roy reached 100,000 miles he was still running on the same oil without a change. By changing his oil filters every 20,000 miles, he saw additional savings of approx. $700.00 annually.

Nelson Trucking hauls a variety of products including heavy equipment and wood. Nelson likes to keep a tight schedule and guarantee punctual delivery times, so he relies on AMSOIL to keep his trucks in top condition.

"Here in Michigan the weather can become a real enemy, especially when the temperature is 20 to 30 below zero," said Nelson. "AMSOIL has proven to me that it doesn't matter if the temperature is hot or cold, it can stand up to whatever Mother Nature throws at us."

Postal Service trucking company is on time
Grand Junction, Co - Monty Moore says he needed an edge to make his business, Star Fleet Enterprises, more profitable. Moore and his wife operate highway contract routes for the U.S. Postal Service.

"From early in the morning until evening under all types of driving conditions, our trucks hold very rigid time schedules - schedules that allow very little time fro maintenance. Plus, repair costs were going through the roof."

"I tried AMSOIL products and was impressed! Just after using AMSOIL Diesel Fuel Additive Concentrate, Cetane Boost and Diesel Fuel Modifier, the performance difference in the trucks was like night and day. Once I installed AMSOIL SAE 75w-90 Synthetic Gear Lube and Heavy Duty Grease, the trucks ran like new."

"We have had our drivers and many others comment on how well the vehicles run," said Moore.

Moore has converted all of his vehicles to AMSOIL. "We are continuing to use the fuel additives for the beneficial edge in performance and mileage.

"We are greatly enjoying the difference AMSOIL products are making in our vehicles."

Beer distributors nuts about AMSOIL
Medina, Minn - With the duty of the "King of Beer" cross country, Chester Gustafson was not about to trust his truck fleet to any oil. Gustafson is the fleet maintenance manager for Thorpe Distributing Co., regional distributor of Anheuser-Busch products. Gustafson has the entire fleet running with AMSOIL synthetic lubricants.

"I'm impressed" said Gustafson, "First we've reduced repair costs significantly. We save $5,000.00 for every overhaul we don't do, and save even more on reduced downtime. Second, we cut our capital costs and now buy trucks as old as seven years. With the proper maintenance using AMSOIL lubricants, we keep them on the road without any driveline maintenance for an estimated 10 years. We've never lost a U-Joint."

Gustafson has been using AMSOIL products since 1983. He has 22 International DT466 beverage trucks and 2 Ford trucks completely converted over to AMSOIL.

The engines use AMSOIL 15w-40 Heavy Duty Diesel and Marine oil. The transmissions are filled with AMSOIL Synthetic ATF fluid. AMSOIL Series 2000 75w-90 Gear Lube is found in the differentials and AMSOIL Multi-Purpose Grease in the wheel bearings. His fork lifts use AMSOIL Hydraulic oil.

He has always changed the oil at 24,000 miles/two years even though the oil kept testing okay for continued use. He plans on stretching it out to 36,000 mile/three year intervals.

Semis going 200,000 miles on one oil change
Danny Howell, Director of Maintenance for Dallas Carriers Corp, Rockwall, Tx, conducted a demonstration in which 2 semis were installed bumper-to-bumper with AMSOIL lubricants.

AMSOIL 15w-40 Heavy Duty Diesel and Marine oil was put in the engines. AMSOIL 85w-140 Gear Lube was installed in the transmissions, rear ends and the power trains.

Periodically, Howell sent samples for oil analysis. The results showed that both the AMSOIL 15w-40 and 85w-140 were serviceable after 200,000 miles. Howell says both the rear ends and transmissions operated like new with the AMSOIL 85w-140.
